METHODS AND DEVICES FOR CUTTING TISSUE - A method of removing material from a blood flow lumen generally includes providing a device having a cutting element and an opening, advancing the device through the blood flow lumen to a site where material is to be removed, forcing the opening toward a wall of the site where material is to be removed, and moving the cutting element and the opening so that material in the blood flow lumen is cut by the cutting element and directed into the opening for removal as the cutting element and opening are moved through the blood flow lumen. In some embodiments, the device may be deflected or bent to force the opening toward a wall to remove material. The cutting element may be rotatable and may have an axis that is movable, that is not parallel to the longitudinal axis of the device, or both.

Image Derived Input Function For PET Lung Assessment - An input function indicative of a time-activity curve in pulmonary arterial plasma is produced from a series of PET image frames in lieu of manual blood sampling. Two manually acquired blood samples are input along with pixel values of a blood pool region of interest (ROI) in the PET image frames into a two-parameter model of the ROI's time-activity curve. In an iterative process the model converges to accurately indicate the amount of

METHODS AND SYSTEMS FOR OCCLUDING COLLATERAL FLOW CHANNELS IN THE LUNG - The lateral flow between adjacent lung segments is occluded by blocking collateral flow channels with particles. A gas flow is established from one lung segment through the flow channels in an intermediate fibrous septum, and out through the adjacent lung segment. Particles entrained in the gas flow become lodged in the collateral flow channels to eventually block flow.

GREY WATER INTERFACE FOR HIGH FLOW APPLICATIONS IN VACUUM SYSTEMS - Embodiments of the present invention relate generally to a flow control unit for controlling liquid flow in a vacuum waste system. In one embodiment, the flow control unit provides a series of valves that direct liquid flow. The unit may also have an intermediate transfer tube that holds a portion of the liquid to be directed, prior to delivery of the liquid to left and right transfer tubes. In one embodiment, the unit may be installed on board a passenger transport vehicle. A particularly beneficial use of the flow control unit is on a private aircraft for use as a shower control unit.

Modular and Expandable Irrigation Controller - Described herein are several embodiments relating to modular irrigation controllers. In many implementations, the irrigation controllers are modular in that various functional components of the irrigation controller are implemented in removable modules that when inserted into position within the controller, expand the capabilities of the controller. Also described are various different types of expansion modules that may be coupled to the modular controller, having as variety of functions and features, as well as related methods of use and configuration of these modules in the controller. In some embodiments, authentication procedures are provided for one or both of a modular irrigation controller and an expansion module to determine if they are authorized to operate together.

POST COVER WITH INTERCHANGEABLE ADVERTISING HOLDER - Non-illuminated and illuminated post-cover displays include a generally cylindrical body having and open lower end adapted for placement over a post extending upwardly from a ground surface. The upper end of the body includes an advertising holder comprising a transparent or translucent form having an open top and an inner surface to receive an insert bearing textual or graphical material visible through the transparent or translucent form when installed. A cap is provided to close off the open top of the transparent or translucent form. The cap may be removable, allowing the insert to be changed, or it may be permanently affixed to the transparent or translucent form. The body and transparent or translucent form may be fabricated as an integrally molded article or portions may be assembled. In the preferred embodiment, the transparent or translucent form is generally cylindrical and the insert is a flexible sheet. In the non-illuminated embodiment the insert may be opaque. In the illuminated embodiment, however, the insert contains one or more transparent or translucent portions and the cap includes a light source to back-light the insert through the transparent or translucent form.

EXTRUDED PLASTIC U-CHANNEL SIGN POST COVERS - Covers for U-channel or C-channel sign posts comprise an extruded hollow plastic form having a length, the form in cross-section including a generally flat front wall and opposing generally flat side walls. Each side wall converges toward the other at an angle from the front wall to a back section having a width less than the front wall, thereby forming a generally trapezoidal interior. Each side wall is bent toward the other to form overlapping portions that make up the back section. In the preferred embodiments, the front wall further includes a co-extruded reflective, fluorescent, phosphorescent or colored lengthwise strip of material to enhance visibility, and the back section further includes an engagement mechanism between the overlapping portions including one or more sets of engaging barbs. The back section may further include a rearward wall extending from one of the overlapping portions and folded over the overlapping portions forming a rearward wall to assist in maintaining the engagement of the barbs.

MODULAR POST COVERS - A modular system includes a plurality of polymeric panels, each panel having a thickness, a length, and first and second opposing parallel side edges defining a width. The first side edge of each panel includes a lengthwise receptacle, while the second side edge of each panel including a lengthwise bead. The bead and receptacle are physically dimensioned such that the receptacle of one panel receives the bead of another panel in interlocking cooperation, thereby enabling multiple panels to be interconnected to surround a vertical member. In one embodiment, each elongated receptacle includes a lengthwise cylindrical cavity having an inner diameter accessed through a lengthwise slot having a width less than the diameter of the cavity. Each elongated bead is a lengthwise cylindrical bead having an outer diameter corresponding to the inner diameter of the cavity, such that the bead is received by the cavity. A different embodiment uses interlocking barbs.
